[PATCH 00/11] More preparatory work for multiparent tree-walker

[Kirill Smelkov <kirr@mns.spb.ru>]

Here I'm preparing tree-diff.c to be ready for the new tree-walker, so that the
final change is tractable and looks good and non noisy. Some small speedups
are gained along the way. The final bits are almost ready, but I don't want to
release them in a hurry.

Please apply and thanks,
Kirill

Kirill Smelkov (11):
  tree-diff: show_tree() is not needed
  tree-diff: consolidate code for emitting diffs and recursion in one place
  tree-diff: don't assume compare_tree_entry() returns -1,0,1
  tree-diff: move all action-taking code out of compare_tree_entry()
  tree-diff: rename compare_tree_entry -> tree_entry_pathcmp
  tree-diff: show_path prototype is not needed anymore
  tree-diff: simplify tree_entry_pathcmp
  tree-diff: remove special-case diff-emitting code for empty-tree cases
  tree-diff: rework diff_tree interface to be sha1 based
  tree-diff: no need to call "full" diff_tree_sha1 from show_path()
  tree-diff: reuse base str(buf) memory on sub-tree recursion
